Trade union pluralism
Trade union pluralism is understood to mean competition between different trade unions. Thus, supporters see trade union pluralism as a logical consequence of the social pluralism of a liberal democracy.
While pluralism is generally uncontroversial in the economic sphere (protection of competition-ban on cartels-press, etc.) or among political parties, opinions differ on trade union pluralism. Critics accuse trade union pluralism of weakening trade unions and thus workers because it fragments trade unions. They point to the united front of the employers, which must be countered by united trade unions. The transfer of the principle of competition to the idea of trade unions is a purely mechanistic approach that ignores the real background of the meaning and benefit of trade unions.
